Littelfuse Remote Indication and Monitoring
Roll Over to Zoom
The Informer is a hand-held diagnostic tool designed for use with single-phase models equipped with infrared LED transmitters (111-Insider-P; 231-Insider-P; 232-Insider; 111P; 233P; 233P-1.5; 234-P and 235P). The Informer uses an infrared receiver to access information sent from the relay which can be helpful for troubleshooting the system. Each Littelfuse single-phase relay model, equipped with an infrared LED, transmits valuable information from the device. To retrieve this information, the Informer’s receiver must be directed toward the relay’s LED transmitter and be within 8 feet of the unit. The green COMM STATUS light indicates when the Informer is receiving data from the relay. If communication is lost, the Informer will display the last values it received. The Informer will automatically shut off after 2 minutes of non-use. An infrared adapter (IR Kit-12) is included with all new and updated Informers. This adapter allows communication with the relay without opening the panel door.
